Texas Instruments TPS62300EVM-085

Overview

TPS62300EVM-085 from Texas Instruments is an evaluation module designed to characterize and validate four independent 3-MHz synchronous step-down converters-two adjustable (1.8 V and 1.5 V) and two fixed-output (1.5 V and 1.6 V)-each supporting up to 500 mA output current with input voltage range 2.7 V to 6.0 V. It enables rapid prototyping of low-voltage, high-efficiency power rails for portable and space-constrained applications.

For engineers reviewing the TPS62300EVM-085 datasheet, TPS62300EVM-085 board layout, TPS62300EVM-085 schematic, or TPS62300EVM-085 BOM, this EVM provides validated reference designs, jumper-configurable operating modes (PWM/PFM), external clock synchronization capability, and full traceability of component placement and routing for TI's TPS6230x buck converter family.

Technical Context

The TPS62300EVM-085 integrates four discrete TPS6230x buck converter channels on a single 2.455" × 1.89" PCB, each with dedicated input/output connectors (J1–J5, TP1–TP12), test points, and configurable jumpers (JP1 for enable/disable, JP2 for mode selection). Converter 1 supports external voltage control via Vadj (FB pin), while converters 2–4 are hardwired for PFM operation and always-enabled functionality.

Board-level design follows high-frequency switch-mode layout best practices: minimized high-di/dt loop areas, ground-shielded feedback traces, single-point grounding, and optimized thermal routing. The EVM accommodates QFN-10 (U1) and CSP-8 (U2–U4) packages and supports output voltage adjustment from 0.6 V to 5.4 V on adjustable channels using external resistor dividers per SLVS528.

FAQ

What is the primary purpose of the TPS62300EVM-085?

The TPS62300EVM-085 is an evaluation module used to assess performance, layout, and configuration options of the TPS6230x family of 3-MHz synchronous buck converters. It hosts four independent channels-two adjustable and two fixed-output-with full access to enable, mode, and feedback control signals, enabling engineers to validate real-world power delivery behavior before final design integration.

Can the TPS62300EVM-085 be used to evaluate other TPS6230x devices beyond those pre-installed?

Yes. The TPS62300EVM-085 supports device substitution: U1 (QFN-10) and U2 (CSP-8) positions accept alternate TPS6230x variants. For fixed-output ICs, R1–R3 and C3 (converter 1) or R4–R5 (converter 2) must be removed. The EVM's schematic and BOM in SLVU115 confirm mechanical and electrical compatibility across the family.

How do I configure the TPS62300EVM-085 for external clock synchronization?

To synchronize converter 1 to an external clock, remove the jumper from JP2 and apply the clock signal directly to the MODE pin. This overrides internal oscillator control and aligns switching edges with the external source-critical for noise-sensitive systems or multi-rail coherence. The TPS62300EVM-085 User's Guide (SLVU115) details timing constraints and signal level requirements.

What are the input and output connection methods on the TPS62300EVM-085?

The TPS62300EVM-085 uses labeled 2-pin headers (J1–J5) and test points (TP1–TP12) for all input/output connections. J1/J2 supply VIN/GND to converter 1; J4/J5 deliver VOUT/GND. Identical labeling applies across all four converters, with dedicated TP pairs for probing without loading sensitive nodes-enabling safe, repeatable bench characterization of each channel independently.

Does the TPS62300EVM-085 include layout guidance for production designs?

Yes. The TPS62300EVM-085 User's Guide (SLVU115) includes top/bottom layer routing diagrams (Figures 1–2), assembly drawings (Figure 3), and a complete schematic (Figure 4). These resources illustrate high-frequency layout techniques-including minimized switching loops, ground shielding of FB traces, and single-point grounding-directly applicable to production PCB design for TPS6230x-based power stages.
